MACHINE FOR HARDENING HACKSAWS.

Specification of Letters Patent,

Application filed February 9, 1918. -Seiial 116.2161421.

` To all whom t may concern Be it known that I, CARI. L. EmosoN, a subject of the King of Sweden,residing-at Longmeadow, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Machines for HardeningHacksaws, of which the following is a specification.

My invention relates to improvements in machines for hardening thin, steel implements, such as and more particularly hacksaws, and resides in automatic means for removing the links, which are used toconnect the hacksaws during the hardening operation, and disengaging or disconnecting said hacksaws, together with the hacksawactuating mechanism of the machine, and such auxiliary and subsidiary parts and members as may be needed or desired in order torender the new features practicable and efficient, all as hereinafter set forth.

In the process of hardening objects such as hacksaws, it is customary to form a chain of such objects by connecting the objects with links. This'is done so that the obj ects can be drawn through the furnace of the hardening machine. As this cha-in emerges from` the machine, after passing through the furnace, it is necessary, of course, to remove the links and so disconnect the now hardened objects, said objects being then taken away and said links being ready to be used over again in the 4formation eitherv of another chain or of a continuation 'of that from which they have been removed, and the prima-ry object of my invention is to provide, at the delivery or rear end of said machine, comparatively simple, yet highly efiicient and practicable, means for automatically removing such links as fast as they arrive at a point Where they are no longer required as chain-forming elements and their removal is feasible.

Occasionally a link becomes worn or distorted in'such a manner that its removal is not readily accomplished by the automatic means which I have provided for that purpose, wherefore another object is to provide, further, safety means whereby, upon failure of a link to become dislodged or detached from the chain, the latter continues--in-'a''e` forward course, without the members thereof, wh-ichhave passed from between the feedsrolls of the machine, pilin up or bunchingitogether, and so becoming dame' agedlor doing --injury to the machine, until the refractory link can berremovedby hand. Although it-is only infrequently that allink has to4 be-rem'ovedin this manner, the aforesaid safety means is an essential feature as a preventive against clogging or blocking tl'ie=passage or channel for the chain at its exit terminal, and which makes it possible to take out the link by hand at a convenient time and lace.

Othero jects and advantages will appear in the course of the following description.

A preferred embodiment of the invention, wherebyI attain the objects andvsecure the advantages of the same, is illustrated in the accompanying drawings, and I will proceed to describe said invention with reference to said:drawingspalthough it is to be understood that thefform, construction, arrangement, etc., of the parts in various aspects are not material and may-be modified without departing from the nature of said invention.

In the'drawings, in Whichrlikeinumerals designate like parts throughout the several views, A'Figure 1 is a front side elevation of a hardening machine equipped with the invention as aforesaid, themiddle portions of the-frame and furnace `being broken out and the `frontend terminals of the guide members at the front end of the machine broken of- 'to economize space; Fig. 2,' an enlarged detail in elevation of portions of two hacksaws-anda link connectingthe same; Fig. 3, anenlarged back side elevation of the nevv` members-and of' parts of the old machine to which `said members are attached and with which they are closely associated; Fig.. 4, anenlarged top plan of said members and parts; Fig. 5, a transverse, verti cal vsection through the attachment, taken on lines 5 5, looking in the direction of the associated arrow, inFig. 3; Fig. 6, a longitudinal, vertical section through said attachment, on lines Gf, looking in the direction of the associated arrow, Fig. 4; Fig. 7, ari-enlarged bottom' plan of the knock-out for thellinksv; Fig. 8, an enlarged, rear-end elevation lof said attachment, the knock-out being shown down in normal `position in 'section cutting Figs. 10 and 11, and taken on a plane which is about on the level with the top of the element 2 shown in Fig. 10.

The present invention is in the nature 0f an improvement of the machine which forms the subject of United States Letters Patent No. 1,150,511, and theold parts of the machine which I have shown and will presently describe brieiy are similar to those which appear in said patent.

Although this machine, including the new features, is designed especially for handling hacksaw blades, hereinafter referred to simply as saws or blades, in the process of hardening such saws or blades, it is to be understod that said machine may be employed to handle any other objects for which it is found to be adapted, as hereinbefore intimated, wherefore I do not intend to restrict the use of the machine to hardening saws exclusively, and the term saw or blade is to be accepted as meaning anything that can be successfully handled by said machine.

The objects to be hardened in this machine must first be connected end to end to form a continuous chain. This chain may be indefinitely added to at the unhardened termlnal and subtracted from, so to speak, at the harde-ned terminal, hence any number of objects can be handled in one uninterru ted operation.

ortions of two blades in section, and a connecting link 2 are illustrated in Fig. 2. The link 2 is fiat and has converging, downwardly-extending feet 3-3 which enter openings 4 common to blades of the hacksaw type. The blades pass flatwise through the machine, while the links stand vertically above said blades withthe feet 3 extending through the blade openings 4 and below the bottom plane of the blades, substantially as represented in Fig. 2. The feet 3 are enough smaller than the openings 4 to enable said feet to be readily inserted in and withdrawn from said openings, and the feet of each link must be spaced apart sufficiently to al low for the relative longitudinal movement of the blades 1 when they are connected and disconnected, such movement being necessary on account of the convergence of said feet. When the blades are drawn forward, the adjacent edges of the openings 4 through which the feet of a link pass are in engagement with the inner or adjacent edges of said feet, arid detachment of said link is prevented; and, when said-blades are pushed forward, the opposite edges of said openings are in engagement with the opposite or outer edges of said feet, and said link can be most readily detached.- Initially the links afford a convenient means for easily and quickly connecting the blades to form and maintain the chain.

Passing now to the machine and considering first the old parts, it will be observed that the same include a horizontal frame 7 supported on legs 8) a front-end supporting guide 9, a set or pair of guide rolls 10 and two sets or pairs of feed rolls 11, the rolls in each pair being arranged one above and the other below, intermediate supporting guides 12-12, a furnace 13, an oil pipe 14, an air pipe 15, a gear-pump ,16 for the oil, a blower 17 for the air, and other elements of which mention will subsequently be made. The blades 1 move flatwise over the guides 9 and 12, while the parts of the feet 3 which extend below the undersides of said blades travel in longitudinal slots in said guides, such as that represented at 18, in Fig. 4.

The guide rolls 10 are at the front end of the machine, and the feed rolls 11 at the back end. Three brackets 19 are secured to the frame 7 ,to aord supports for the rolls 10 and 11. The upper rolls 10 and 11 are yieldingly forced down onto the lower rolls 10 and 11, or on intervening elements, by means of springs 20 and adjusting screws 21. The guide rolls 10 are not driven in this case, but simply revolve as the chain of blades and links is drawn between them, and these rolls and the feed rolls 11 as well have grooved peripheries to enable said links to pass freely between said rolls and permit the latter to grasp said blades. The rolls 10 and 11 are mounted on shafts 28, and the bearings for said shafts are similar to corresponding bearings in the aforesaid patent. The feed rolls 11 are power driven through the medium of a driving shaft 22, a pulley 23, sprocketwheels 24 and 25, a sprocketchain 25, gears 27 on the feed-roll shafts 28,

andi an intermediate gear 29.

At the front or inner end of the rear guide 12 is a trough 30. The trough 30 opens into a pipe 31 which in turn opens into a tank 32. The gear pump 16 and the blower 17 are driven by a single shaft 33, a pulley 34, and a belt 35. A pipe 36 connects the pump 16 with the tank 32 or with the oil therein. The pump raises oil from the tank 32 and discharges the same through the pipe 14. The pipe 14 branches to provide two points of discharge or outlets 37, one above the other, at the open front end of the trough 30. The oil that enters the trough 36 returns to the tank 32 by way of the pipe 31. The air pipe 15 extends from the blower 17 to a point of discharge or outlet, represented at 38, immediately in front of the upper oil outlet 37.

By-the above-mentioned means oil is apbt its innerterminal mounted on said bracket' plied directly to both the top and bottom surfaces of the blades, after they emerge from the furnace 13, and a current of auprevents the oil from following along said blades toward said furnace.

The furnace 13 is located in the path of the chain between the inner ends of the guides 1Q, but somewhat remote from such ends.

The chain of saws and links is started on the guide 9. Said chain passes between the guide rolls 10, over the front guide 12, through the furnace 13, under the air current and between the quenching streams or jets of oil, through the trough 30, over the rear guide 12, and between the two pairs of feed rolls 11, such chain being drawn forward by said last-named rolls. Upon exnerg ing from the rolls 11 the chain must be broken up 'by disengaging and removing the links from the blades, and it is here that the new attachment comes into service.

As Previously stated, the rolls 10 are idler guide rolls, instead of feed rolls driven at a slightly less speed than the rolls 11 in o-rder to put a* tension on the ch-ain as heretofore. By the use of idler rolls at the front end of the machine, all danger is avoided of the saws piling up in the furnace and becoming ruined in the event the rear-end rolls fail, as occasionally occurs from some cause or other, to function properly or to feed the chain. If the rolls 11 fail to feed the chain, the latter remains stationary throughout its entire length, sincethe rolls 10 have no Power except that derived' from said chain, whereas the rolls 10, if driven independently of said chain, would force the chain along from the front end of the machine, with disastrous results. The rolls 10 grip the chain with sufcient force to hold it taut between this pair and the rolls 11, wherefore there is no need of the additional strain that would be put upon lsaid chain in the event said rolls l() were driven by power other than the chain and at a less rate of speed than said rolls 11.'

Although this is a feature apart from the link remover at the rear endof the machine, it is important and of value.

The attachment wherewith the saws after being hardened are separated will be described in detail below.

Said attach-ment comprises raising and tipping elements for the links, and also means whereby the tipping element or knock-out is permitted momentarily to be raised out of the path of a link, which sticks or fails to be dislodged by said knock-out, by the link itself.

Specifically and in detail the link remover, including the movable safety element, comprises-.a transverse bracket 39 bolted at 40 to the back side of the rearmost bracket 19, a rearwardlyextending support 41 having and secured thereto by screws 42, endwise '.-ldjustable supporting plates 43--43 also mounted on said bracket, the adjustment of said plates being transverse of the machine, front and rear guide plates 44 and 45, respectively, mounted on adjacent terminals of said first-named plates and secured thereon by screws 46, said plates 44 and 45 forming with said support 41 a. channeled guide for the saws, and a. knockout 47 rigidly attached by screws 48 to the rear ends of a pair of arms 49, which latter have their forward ends mounted t0 rockv on. a stud 50 which extends to the left or rearwardly from an upright 51 that is bolted at 52 against the inner face of said bracket. The bracket -39 projects forward of the front side edge of the rearmost bracket 19, and the upright 51 is ibolted to such projecting part in front of said bracket 19 or said edge thereof.

The top of the support 41, at the inner terminal, has an upwardly and rearwardly inclined surface or pant 53-see Figs. 5 and The back side edge of the support 41 is cut down slightly from above, as shown at 54 in Figs. 4, 5, 8, and 11 to afford clearance for the teeth of .the saws, as the latter move over said support with their teeth toward the rear, which is the position of said saws as they are actuated through the machine. Said teeth project a little .below the bottom plane of the bodies of the saws, and above the top plane of said bodies as well, as i1lustrated in Fig. l11. In this connection it may be observed that the knock-out 47 is designed to bear on the saws, as will presently be eX- plained, and that the base of said knock-out is suiiiciently narrow for the upwardly-pr@ jecting portions of the saw teeth to clear the same, even such portions of the teeth on the narrowest saws which the machine handles, see especially Fig. 11.

Each plate 43 is heldin place on the bracket 39 by means of a key 55, and a bolt 56, nut 57, and washers 58-58. The two keys 55 are received Vin alining slots59 and 60 in the upper and under sides of the bracket 52 and the plates 43, respectively, and prevent said plates from turning on the bolts 56. The slots 59 and 60 open through the ends of the bracket 52 and lthe outer ends of the plates 43. The two bolts 56 pass throu h' longitudinal. slots (i1-61, Fig. 5, in t `e bracket 39, and 'through the plates 43, and the two nuts 57 and four washers 58 are applied in the usual manner to said bolts. When the nuts 57 are tight the plates 43 are held against endwise movement. Upon loosening the nuts 57 the plates 43 and the attached guide plates 44 and 45 can be moved closer together or farther apart, so adapting the channeled guide, formed by said guide plates with the support 41, t0 blades of any given width. After such adjustment the nuts- 57 are netightened to hold,

with the aid of the keys 55, the adjustable members rigidly in place.` v

The adjacent longitudinal edges of the guide plates 44 and 45 extend over 'thecontiguous edges of the support 41 more or less according to the nature of the adjustment of said plates, and receive between them and guide the blades as they are actuated over said support. An opening 62, Fig. 4, is made in the back plate 45 behind the outer terminal portion of the knockout 47, transversely, and a pan 63 is supported from the rear end of the frame 7 under said openin as shown in Fig. 1.

The knock-out 4 is a block or bar having in the bottom thereof a longitudinal slot 64, which slot opens at one end through the forward or inner end of said bar, and adjacent to the other end through an opening in the back side of said bar. The slot 64 is of a width to accommodate the link 2, and the opening 65 is large enough for said link to pass through flatwise. Forming the rear or outer end of the slot 64 is a deiiector 66, which is simply an oblique part of the knock-out bar having an inclination from above downwardly and rearwardly in both directions, that is, downwardly and toward the rear or outer end of said bar, and downwardly and toward the back side of said bar. The knock-out 47 is positioned, by the arms 49, directly over the support 41, at and adjacent to the inner or front terminal portion thereof, so that it can rest on the blades as they pass over said support and between the plates 44 and 45, and the opening 65 and the deiiector 66 are situated adjacent to the opening 62 in said plate 45. A rearwardly-extending oblique nger or guard 67 projects from the outer end of the knock-out bar over the opening 62. l

The stud 50 is rigidly attached at its inner terminal to the upper terminal of the upright 51, by means of a shoulder 68 on said stud, on one side of said upright, and a nut 69 on said stud, on the other side of said upright, as best shown in Fig. 9. A pin 70 through the free terminal of the stud 50 prevents the arms 49, which are mounted on said stud between the shoulder 68 and said pin, from becoming displaced.

The arms 49 are provided on top with vertical pins 71 to receive and hold in place weights, in the event additional force be required to hold the knock-out 47 down on the saws and links. Ordinarily the combined weight of the knock-out and the arms 49 is suicient, without augmenting the same in the manner just mentioned.

When the chain of blades (1) and links (2) is introduced into the machine, the leading portion of said chain, after assing between the second or rear pair ofJ feed rolls 11, is led out Aonto the support 41, between the guide plates 44 and 45, the knock-out 47 being momentarily raisedto enable said chain to pass under the same. It is understood, of course, that the plates 44 and 45 have been adjusted, if necessary and to whatever extent may be necessary to receive between them the blades in the chain, and permit said blades to move freely over the support 41, such'adjustment being accomplished by loosening the nuts 57 and in the manner previously explained. Now, as the feeding mechanism of the machine, which has been set in motion, continues to act on the chain, the latter is drawn through the furnace 13' and pushed out over the support 41. that portion of the chain that is on the support 41 crowds the blades and links forward, in the direction of travel of said Ichain, so that, as each link passes up the inclined surface 53 of said support, such link ordinarily can be and is easily forced upwardly, the feet 3 of the link rising in the blade openings 4, in which they are located, and the link is thus elevated until, when the link rides 0H of said inclined surface onto the level part of said support, the bottoms of said feet are on the same plane with the undersides of the blades connected by the link-see Fig. 10. The link thus elevated is in the slot 64 in the knock-out 47, and, when the foremost end, in the direction of travel, of said link encounters the deiiector 66, said link is by said deflector tipped transversely backward and out through the opening 65, in the manner illustrated in Fig. 11, the feet of said link leaving the aforesaid blade openings. The link at once drops down through the opening 62, in the plate 45, into the pan 63, from which it is subsequently taken to be used in making chain at the other end of the machine. The guard 67 prevents the link from being projected beyond the opening 62 tojfind lodgment on the plate 45, and thereby permits of both a shorter opening 62 and pan 63 than might otherwise be required. It is to lbe understood, however, that even in the present construction the link may drop through the opening 62 without the aid of the uard 67.

As the c ain continues to be fed each succeeding link is removed by the knock-out 47, until a refractory link, that is to say, a link which is worn, mutilated, warped, or otherwise defective, arrives at the deflector 66. In this case the deflector 66 fails t0 dislodge the link, and the relative coaction of the deflector and link is in a way reversed, since the latter now acts on theformer to raise it, instead of being itself acted on in a manner which casts it out of the passage 64 through the opening 65 in the knock-out 47. The link in question, when it encounters the inclined surface of the deiector 66, forces the knock-out 47 up- The pushing action of the rolls 11 on 'ward-ly, and rides under said deiiector and out onto Ithe rearh part of the support 41, where said link is removed by hand before arrivin at the extreme rear end of said support. soon as the link passes clear of the knockout 47 the latter descends again into normal position onto the parts below. The knock-out 47 or rather the arms 49 to Which said knock-out is attached rock on the stud 50.

When the knockout 47 is in normal position it holds the blades down on the support 41, as said blades are pushed along, and automatically detachee all links, except those which have become too firmly fixed in the blades to be dislodged by said knock-out. And when one of the refractory links fails to be ejected through the exit opening 65, such link momentarily raises the knock-out, as explained above. Normally and the greater part of the time the knockout is down in operative position, and at no time is it out of such position when required to eject a loose link.

The base of the knock-out 47 is narrowed so as to leave ample space on each side for the adjustment of the plate (44 or 45) on that side, and it is in the back side space thus provided that the upwardlyprojecting portions of the saw teeth are received and travel. The required adjustment of the plates 44 and 45 is comparatively slight.

As fast as the links are removed by the knock-out from the saws, the saws behind close up on those ahead, in the direction. of their travel, so that a continuous line is maintained out to the rear end of the support 41` Consequently the bottom of the rear or free end of the knock-out 47 always bears on one or two of the saws which are passing over the support 41 and under such end, except during the short interval that said knock-out is raised by a refractory link. Each saw, before'it passes clear of the knock-out, comes toiastop and remains stationary in the grasp of said knock-out until its companion fol lowing, from both of which it is to be assumed the connectin link has just been removed, contacts wit said first-named saw and pushes it along. Or, in the case of a refractory link, there is a saw under the knock-out when the latter comes down after the link has cleared the same. There is, therefore, no opportunity for the knock-out to dro -down between the adjacent ends of twoladrjacent` saws and so block the passage. From the foregoing it is seen that the machine when in operation turns out a continuous line of hardened blades, disconnecting them automatically at the end of the operation, except in the infrequent instances when thealinksstick, and even then there is no sto pa e, clogging, or other interference wit "wt, e continuous o eration of the maohir'tgibut olily'thefslig t trouble41 incident. to Y the removal of such links by hand. The capacity of the machine for turning out the hardened blades is practically unlimited, inasmuch as the hardening operation may be continued as long as the linked blades are fed into the machine, the operating parts of the machine being capable of handling and acting; on a practicallyr limitless number of blades.

Links which have lost the bottom portions of their feet, so that the elevating medium, which consists of the inclined surface or part 53, is of non-effect, are removed by the knock-out, in the same manner as are the links that are whole or perfect and need first to be elevated.

The bottom edges and the top, inside, of the slot 64 in the knock-out 47. at the front end or mouth. thereof, may be flared or curved upwardly. as indicated at 90 in Fig. 6, in order to facilitate the entrance beneath said knock-out of the saws and entrance to said slot of the links.
